Airdropped cargo is sometimes bouncing off the ground and exploding

[KarlMoebius]

Arma 3 Version: 1.72 (stable)
CBA Version: 3.4.0 (stable)
ACE3 Version: 3.10.2 (stable)

Mods:

- CBA_A3
- ace
- @RHSUSAF
- @RHSAFRF
- ACE compat for USAF/AFRF

Description:

• When a vehicle is air-dropped it spawns a parachute and drifts down. When the vehicle lands, it seems once the parachute attachment point of the vehicle and the terrain level are equal, the parachute lets go, which leaves some vehicles half or fully inside the terrain when the parachute lets go, and then arma physics take over. Once Arma takes over, the vehicle immediately bounces into the sky, lands and explodes.

Steps to reproduce:

• Put two vehicles in a flying vehicle via ACE3. (in my example a RHSAFRF BTR-80A inside a RHSUSAF C-130, manipulating the BTR to take 1 space, instead of -1 and unload able, so it loads and unloads quickly)
• Take off.
• @ 1000m indicated altitude/ ~300km/h indicated air speed, initiate airdrop through the ACE3 cargo interface. (Testing with lower altitudes has proven problematic, sometimes the vehicle's parachute spawns sideways or at an angle, and the vehicle does not straighten out, or oscillates back and forth during descent)
• Using zeus, or some other method, position yourself near the falling vehicles.
• Watch as some vehicles impact and keep going into the ground, but once the vehicle attachment point of the parachute is equal with the terrain, the parachute lets go.
• Arma physics takes over and bad things happen.

Is this only me?

SIMILAR problem regarding airdrops in general using latest ace3 and CUP-chernarus... except for the fact, that boxes and crates fall through the ground and are no longer reachable

Confirmed having the same issue on the object B_supplyCrate_F, in multiplayer (dedicated).

I believe the issues lies here: https://github.com/acemod/ACE3/blob/master/addons/cargo/functions/fnc_paradropItem.sqf#L68

Perhaps the parachute needs to be attached 1 above the object, as opposed to the object -1 below?
